hideously

This adverb carries a strong negative charge, moving beyond simple ugliness to imply a sense of shock, horror, or visceral repulsion. It is frequently used to describe aesthetic failures that are so severe they become offensive or grotesque.

In a non-visual sense, the word functions as an intensifier for negative attributes, similar to "outrageously" or "appallingly." When paired with terms like "expensive" or "wrong," it suggests that the degree of the quality is not just high, but unacceptable or morally offensive.
